4. MEASURING PROCEDURE

4-1 Pay attentions for the measurement

1)When make the fruit hardness testing, it always use

compression function, the display will show the '" - "

mark automatically.

Remark :

The meter can use the " Tension " measurement,

however for the fruit hardness measurement is not

use this function typically.

2)Pressure head and fruits should be vertical surface.

When make the measurement, the Sensing Head

along the tip should be on a line with measuring fruits

( ref. Fig. 2 )

Fig. 2

3)Rotate the Sensing Head is prohibited. Some certain

angles between Sensing Head & measuring object

are not allowed ( ref. Fig. 3 ).

Fig. 3

4-2 Normal Measurement

1)Slide the " Power Off/On/Peak Hold Switch " ( 3-8, Fig. 1 )

to the " On " position.

0 = Off, 1 = On

2)Determine display unit of g, oz or Newton by selecting

" Kg/Newton/LB Unit Switch " ( 3-7, Fig. 1 ).

3)Connect " Sensing Head " ( 3-1, Fig. 1 ) with proper "

Adapter " ( 3-11 to 3-14, Fig. 1 ) and the " Measuring

Object " should be in straight line. Don't give any force in

standby mode..

4)" Zero Adjust " by pushing " Zero Button "

( 3-6, Fig. 1 ) before every measurement.

5)Start measurement by giving force (push or pull), then the

LCD will display the Average reading value.

During the measurement, if intend to change

the display direction, just push the " Reverse

Button " ( 3-5, Fig. 1 ) once.

*There are two kind sampling time of display, FAST

and SLOW. Push the " FAST/SLOW Button " once

( 3-4, Fig. 1 ), if the upper left corner of LCD show

" FAST " ( Fast Indicator, 3-3, Fig. 1 ), then the

display reading is under the operation of fast

sampling time.

*If the upper left corner of LCD not show the

" Fast Indicator " ( 3-3, Fig. 1 ), the display

reading is under the slow sampling time.

*Over range display of tension function, LCD

will show " "

*Over range display of compression function, LCD

will show " "

4-3 Peak Hold Measurement

The meter can measure the peak value of force both of

tension & compression operation. The operation

procedures of Peak Hold Measurement are same as above "

4-2 Normal Measurement " but should slide the " Power

Off/On/Peak Hold Switch " ( 3-8, Fig. 1 ) to the " PEAK H. "

position.

Slide the " Power Off/On/Peak Hold Switch " ( 3-8, Fig. 1 )

to the " On " position will cancel the peak hold function.

4-4 LCD Back Light On/Off

During the measurement, press and hold ( > 2 seconds )

the " Button " ( 3-15, Fig. 1 ) until LCD Back Light

is ON, then it will be off after a period time.

several seconds then off automatically

5. BATTERY REPLACEMENT

1)When the LCD shows " Lo ", it is necessary to replace

the batteries. However, in-spec. measurement may

still be made for several hours after low battery

indicator appears before the instrument become

inaccurate.

2)Take out the battery cover ( 3-10, Fig. 1 ) away from the

instrument and remove the batteries.

3)Install the batteries ( 6 x 1.5 V AA, UM-3 ) correctly

into the battery case.

6. RS232 PC SERIAL INTERFACE

The instrument features an RS232 output via 3.5 mm

Terminal ( 3-17, Fig. 1 ).

The connector output is a 16 digit data stream which can

be utilized to the user's specific application.

An RS232 lead with the following connection will be

required to link the instrument with the PC serial input.

Meter PC

(3.5 mm jack plug) (9W 'D" Connector)

Center Pin................................

Pin 2

Ground/shield.............................

Pin 5

The 16 digit data stream will be displayed in the

following format :

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Each digit indicate the following status :

D0 End Word

D1 & D8 Display reading, D1 = LSD, D8 = MSD

For example :

If the display reading is 1234, then D8 to D1 is : 1234

D9 Decimal Point(DP), positision fron right to the

left

0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP

D10 Polarity

0 = Positive 1 = Negative

D11 & D12 Anunuciator for Display

g = 57 Newton = 59 oz =58

Kg = 55 LB = 56

D13 1

D14 4

D15 Start Word

RS232 setting

Baud rate 9600

Parity No parity

Data bit no. 8 Data bits

Stop bit 1 Stop bit

7. MOUNTING HOLES & OPTIONAL

TEST STAND

Fruit hardness tester is a precise instrument, best results

are obtained when the gauge is fitted to a test stand.

Mounting holes ( 3-9, Fig. 1 ) are provided on the back of

the gauge for easy stand mounting.

Optional Test Stand & accessory :

*TEST STAND, Model : FS-1001

Test stand, cooperate with Force gauge, whole system

will be become the useful tool for material's tension &

compression analysis.

Size : 630 x 250 x 230 mm. Weight : 7.02 Kg ( 15.4 LB ).
